LASIK or Lasik (Laser-Assisted in situ Keratomileusis) - Eye Care & Vision Glossary Excerpt
LASIK or Lasik (Laser-Assisted in situ Keratomileusis), commonly referred to as laser eye surgery, is a type of refractive surgery for the
correction of myopia, hyperopia, and astigmatism. The LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to
reshape the eye's cornea in order to improve visual acuity. For most patients, LASIK provides a permanent alternative to eyeglasses or contact
LASIK is most similar to another surgical corrective procedure, photorefractive keratectomy (PRK), and both represent advances over radial
keratotomy in the surgical treatment of refractive errors of vision. For patients with moderate to high myopia or thin corneas which cannot be
treated with LASIK and PRK, the phakic intraocular lens is an alternative.
Since 1991, there have been further developments such as faster lasers, larger spot areas, bladeless flap incisions, intraoperative corneal
pachymetry and "wavefront-optimized" and "wavefront-guided" techniques. However, use of the excimer laser risks damage to the retina and optic
nerve. The goal of refractive surgery is to avoid permanently weakening the cornea with incisions and to deliver less energy to the surrounding
The iLASIK Procedure is the result of a decade's worth of technical refinement; it combines all of the most advanced all-laser LASIK technology in
one efficient LASIK procedure ... It simply doesn't get any better, so now's the time.
